Will two separate 50db sound constitute 100db sound?
No, two separate 50 dB sounds do not add up to 100 dB. The decibel scale is logarithmic, not linear, so if two sound sources with the same intensity are combined, the resulting sound level will be 3 dB higher than the original level (for identical sound sources).
What happens when a sound gets louder?
It is the intensity of the sound wave. There is however a big difference between sound intensity and loudness. Loudness is measured with a scale called the Decibal scale , which is abbreviated as db in many cases. Your typical rock concert can hit db levels of 125db, and a typical iPod tops out at around 100db. The relationship between loudness and sound wave intensity can be explained by how compact and by wave amplitude. Amplitude is the height of the wave. Sound waves are introduced into a medium by the vibration of an object. For example, a vibrating guitar string forces surrounding air molecules to be compressed and expanded, creating a pressure disturbance consisting of an alternating pattern of compressions and rarefactions. The disturbance then travels from particle to particle through the medium, transporting energy as it moves. The energy which is carried by the disturbance was originally imparted to the medium by the vibrating string. The amount of energy which is transferred to the medium is dependent upon the amplitude of vibrations of the guitar string. If more energy is put into the plucking of the string (that is, more work is done to displace the string a greater amount from its rest position), then the string vibrates with a greater amplitude. The greater amplitude of vibration of the guitar string thus imparts more energy to the medium, causing air particles to be displaced a greater distance from their rest position. Subsequently, the amplitude of vibration of the particles of the medium is increased, corresponding to an increased amount of energy being carried by the particles thus resulting in an increase in the volume or db levels.

At what level can sounds damage ears?
at 100Db sound can start to damage the ears.
What is thecommon-mode rejection ratio of an LF157A at low frequencies?
100dB
How many times more intense is 108 dB than 100dB?
The power is 100.8 = 6.31 times as much.
What is the approximate gain of an op-amp open loop?
It is between 100,000 and 1,000,000 and even more. In dB, it is between 100dB to 120dB.
How many Decibels does a cricket make?

How loud is a vuvezela?
Now a vuvzela is around about 127db. To put that into propectus a petrol chainsaw produces 125db and a Rock concert around 100db. So a vuvzela is rather loud.!!
What is Difference between fade rate and fade depth?
Fade rate is the time to fade a certain amount. For example, Multipath fading on a microwave link may occur at 100dB/sec. Fade depth is the reduction from the normal received level, measured in dB.
What sounds damage the human ear?
Loud sounds above 85 decibels, such as concerts, sirens, and power tools, can cause damage to the human ear. Prolonged exposure to these sounds can lead to hearing loss or other ear-related issues. It's important to protect your ears with earplugs or ear defenders in noisy environments.
What distance increase is needed to reduce a sound's intensity from an initial 100dB to a final 80dB?
Sound intensity is inversely proportional to the square of the distancefrom the source.-- Increase the distance from the source by 10 times.-- Sound intensity decreases to 1/102 = 1/100 .-- 10 log ( 1/100 ) = -20 dB-- 100 dB - 20 dB = 80 dB
How loud are hydraulic boom lifts?
If you think about it the hydraulics flowing in the lines are relatively quiet. the piston lifting or lowering the boom is just as quiet...so where is the noise ? it comes from the pump and the prime mover for the pump..If its a diesel engine its loud.. If its steam driven ,somewhere there is a lot of fuel being burned and that location is loud...If its run by an electric motor and Even if its just in the bypass mode the fluid screaming through the control valves will be loud...So now ,,,Going back to your question ..the boom is practically silent but the prime mover makes the whole thing very loud indeed. 90-100db at times...
Can your own screaming damage your ears?
Yes, if you can produce more than 85dB of noise. The louder the scream above this threshold, the faster you can damage your hearing. At 100dB, it takes about 20min. Normally it is unlikely unless you scream a lot. Opera singers sometimes have hearing damage due to the loudness and time extent of their singing.
